Subspecies
Swee Waxbill (Coccopygia melanotis) and Yellow-bellied Waxbill (Coccopygia quartinia) (Sibley and Monroe 1990, 1993) have been lumped into Estrilda melanotis following Dowsett and Forbes-Watson (1993).
Thought to form a superspecies with Coccopygia bocagei and Yellow-bellied Waxbill (Coccopygia quartinia) and often treated as conspecific, but differ morphologically and in behaviour.
The following 2 subspecies are recognised:
melanotis (Temminck, 1823) - South-central Zimbabwe and south-western Mozambique to southern South Africa.
bocagei (Shelley, 1903) - Angola. Considered by some authors to be a distinct species, Angola Waxbill (Coccopygia bocagei).
